Residents of Hawaii use the shaka to convey the "Aloha Spirit", a concept of friendship, understanding, compassion, and solidarity among the various ethnic cultures that reside in Hawaii, lacking a direct semantic to literal translation. Drivers will often use it on the road to communicate distant greetings along with gratitude.

In California, the shaka sign may be referred to as "hang loose" or "hang ten", both associated with surfer culture. https://en.m.wikipedia.org/wiki/Shaka_sign 🤙🏻
